LOOM.

SPECIFICATION forming part of Letters Patent No. 637,1 13, datedNovember 14;, 1899. Application filed June 17, 1899. Serial No. 720,881.(No model.)

To ctZZ whom, it ntay concern:

Be it known that I, HENRY I. HARRIMAN, a citizen of the United States,residingat New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Looms, of which thefollowing is a specification, reference being bad therein'to theaccompanying drawings.

The invention relates to weft-replenishing looms on the order of thatwhich is presented in United States Letters Patent granted to me June13, 1899, No. 626,834.

My patent just referred to describes and claims certain automaticinstrumentalit-ies which are under the control of weft-indicatingdevices that act to institute the operation of the saidinstrumentalities when the work: ing-weft supply assumes thepredetermined condition calling for a replenishment thereof. Theseinstrumentalities when brought into place operate to occasion asuspension of the weaving, and they effect the replenishment of the saidworking-weft supply during such suspension, after which the weaving isresumed. The said patent presents also provisions for pick-finding, bymeans of which to secure for the reception of the first pick of freshweft after the replenishment a reopening of that shed in the round orcycle of shed formations which was deficient in its supply of weft orfilling at the time of the detecting action of the weft-indicatingdevices which brought about the weft replenishment.

The present invention comprises various improvements which areapplicable to the loom of my patent above mentioned. The saidimprovements will be described with reference to the accompanyingdrawings, in which latter the preferred embodiments of the same areillustrated. For convenience in making clear the connections andrelations in which the improvements are intended or are capable of beingemployed I have shown herein certain portions of the instrumentalitiesand mechanism of my patent, certain features being as in my applicationfor United States Letters Patent filed May 8, 1899, Serial No. 715,907.7

Having reference to the drawings, Figure 1 thereof is a view showing infront elevation portions of a loom having applied thereto the preferredembodiment of my present inven- -which are represented in Fig. 6.

tion. Only such parts of the loom are shown as are required to appear inorder to assist in presenting the nature and relations of the invention,the remainder being omitted in order to secure clearness. Fig. 2 is aview in elevation of the change end of the said loom. Fig. 3 is a viewshowing the hopper or magazine in rear elevation. Fig. tis a viewshowing certain portions of the loom in rear elevation. Fig. 5 is a viewshowing in plan the shedding-cams and certain of the parts which areconcerned in the working thereof and in pick-finding. Fig. 6 isaviewshowing in side elevation the weft-fork at the change end of the loomand certain parts which cooperate therewith. Fig. 7 shows in plan theparts Fig. 8 shows in perspective part of the framework of the loom anda modified arrangement of picking mechanism. Fig. 9 isa View, on anenlarged scale, showing a portion of the lay and certain parts appliedthereto. Fig. 10 is a view in section on line 1O 10 of Fig. 4 on anenlarged scale. Fig. 11 is a view of cam-disk n and its ratchet n Figs.12 and 13 show modified forms of the cam-disk of. Figs. 14: and 15 areelevations of the main-and auxiliary weft-fork devices, respectively.

The drawings show the end frames at a of an ordinary plain loom, aswellas portions of the breast-beam a thereof, portions of the front and rearcross-girths a and a respectively, portions of the crank-shaft b and thecam-shaft c, and the driving gear-wheels b and c on the said shafts.They show also the lay-beam d, a lay-sword d, and one of the pitmen orconnecting-rods d joining the lay with the crank-shaft b.

I have herein illustrated the features of my present invention asembodied in connection 7 with instrumentalities for effecting replenishment of the working-weft supply by ejecting ordischargin'g from the laythe spent or failed shuttle and substituting a reserve shuttle. It is tobe understood, however, that the main features of my invention are notlimited to use in connection with instrumentalities of this precisecharacter or class.

I will first describe briefly the weft-replenishing instrumentalities.

As in my prior patent and application, I have shown herein a store ofreserve shuttles arranged in a hopper or magazine, which is representedat e, the same being located adjacent to the breast-beam at the supplyend 01' change end of the loom. The shuttles in the said hopper ormagazine are indicated at ff, Figs. 1, 2, and 3, while the workingshuttle upon the lay is indicated at f in Figs. 2 and 9.

At the time at which the spent or failed working shuttle f is ejected ordischarged from the lay it is contained within the shuttle-box at thechange end or supply end of the loom and compressed between the swell orhinder g and the shuttle-box front h. (See Figs. 2 and 9.) The binder gis borne against by the protector-finger g, the latter being mounted onan arm 9 of the protector-shaft. (Not shown.) For the purpose ofrelieving the pressure of the swell or binder 9 against the workingshuttle f in order to facilitate the operations of lifting theshuttle-box front, inserting the reserve shuttle, and restoring theshuttle-box front to position the rocker g is provided, it being mountedon the lay at the under side of the lay-beam, adjacent the outer end ofthe protector-shaft, one arm of the said rocker being arranged to actagainst the said arm 9 The rocker g is operated at the required time inthe working of the replenishing instrumentalities through the agency ofa connection 9 extending therefrom, made flexible in part to enable itto pass around a direction-changing guide-sheave at 9 adjacent to thefulcrum of the lay, and joined to a lever g, that is actuated by meansof a cam g on the so-called change-shaft m.

For the purpose of providing for the withdrawal and replacement of theshuttle-box front h the said front is mounted on the forwardly-extendedarms of a rocker h, which is pivoted at 77, in suitable bearings at therear of the lay-beam, the rocker being held in its normal position withthe front 71 in place by means of spring lbs. The rocker h is moved atthe proper time through the agency of a connection it", extending fromits rear arm and made flexible in part to pass around adirection-changing sheave at g, the said connection being joined to alever 71. operated by a cam h on the change-shaftm.

For the purpose of ejecting the spent or failed shuttle from theshuttle-box at the change end or supply end of a loom after theshuttle-box front It has been lifted an ejector-plate -i is mounted toslide forward and back beneath the swell or binder g. For the actuationof the said ejector t' a rocker t" is connected therewith, the saidrocker t" being mounted in bearings t at the rear of the laybeam andbeing acted upon by a spring i which serves to hold the ejector in itsretracted or real-most position, the said rocker being moved at theproper time through the agency of a connection 2' made flexible in partand passing around a direction-changing guide-sheave at g and engagingwith a lever 2' operated by a cam i on the changeshaft m,these ejector-operating arrangements being substantially as in my applicationfor Letters Patent filed May 8, 1899, Serial No. 715,907. I j I For thepurpose of transferring the bottom reserve shuttleffrom the hopper ormagazine 6 to the shuttle-box on the lay after the discharge of thespent or failed shuttle from the latter an injectorj is provided, thesame being mounted on a supporting-arm j, which is pivoted, as at 7' ata point adjacent to the fulcrum of the lay. The injector is moved at theproper time by a connection 7' extending from arm j to a leverj operatedby a camj on change-shaft m. The said cam is constructed to occasion anexcess of movement of the injector in order to insure that thelatter inbeing moved to meet the lay shall find the latter, a spring beingemployed as a part of the connection between arm j and leverj in orderthat it may yield when theinjector brings up against the lay. At itsupper end the injector is furnished with rearwardly-projecting curvedarmsf", constituting supports on which a shuttle may lie as it is beingcarried rearward from the hopper or magazine 6 to the lay. Fingersj areprovided on the injector for engagement with the bottom shuttle in thehopper or magazine in the rearward movement of the injector,'thesefingers being pivoted atj upon the injector and acted upon by a springjwhich permits them to yield as they make contact with the lowest shuttlein the hopper or magazine as the injector returns forward, the injectorbeing thereby permitted to pass unobstructedly beneath the stack ofreserve shuttles as it returns to its normalposition. (Shown in Fig. 2.)Theshuttle-supporting armsj of the injector are disposed to occupy aforwardly-inclined position in the normal position of the latter, andthe lower portion of the shuttle-passage in the hopper or magazine 6 isinclined rearwardly, the bottom of the said hopper or magazine beinginclined downward forwardly, whereby to retain the bottom shuttle frommisplacement. As in my application aforesaid when the injector stands inits normal position at rest the rear portions of its arms extend beneaththe stack of reserve shuttles in the hopper or magazine. The bottomshuttle of the said stack rests on the bottom of the hoppera slightdistance above the upper sides of the said arms, whereby all theshuttles are supported.

As thus far described the devices are or may be substantially as in mypatent aforesaid, except in the respects in which, as indicated above,they are as in my said application.

For the purpose of holding the ejector i locked in its rearward positionout of the way of the shuttle at all times except when the shuttle-boxfront h is lifted I have combined with the same, in accordance with oneportion IIO a rocking shuttle-retainer comprising,

of my present'invention, a lock, which herein is designated la. The saidlock consists, in the form thereof which is shown in the drawings, of acurved finger attached to or forming part of the rocker h. In the normalposition of the rocker h the said locking-finger it projects into a holein the ejector. When the rocker h is turned to lift the shuttle-boxfront, the said locking-finger 7c is withdrawn from the said hole,thereby leaving the ejector free to be carried forward for the purposeof engaging with the shuttle and ejecting the latter from theshuttle-box.

For the purpose of more completely assuring against untimely backwardmovement or escape of the bottom shuttlef from within the hopper ormagazine 6 I have combined with the opening which is provided at therear of the said hopper or magazine, in accordance with another portionof the present invention, as shown in Fig. 3, wings or fingersl Z on arockshaft 1, the said rock-shaft being mounted in bearings Z Z providedon a support l at the rear of the hopper or magazine and provided withan arm I", with which is connected one end of a spring, as Z By means ofthe said spring the wings or fingers Z lare maintained in a position tooppose rearward movement of the bottom reserve shuttle in the hopper ormagazine. The said win gs or fingers, however, are permitted to yield asthe said shuttle is carried rearwardly by the action of the ejector. Theinnermost of the said wings or fingers has the outer edge of the samemade beveled or inclined, as shown in Fig. 3, in order that as thebottom shuttle is transferred from the hopper or magazine to the lay thefilling end issuing from the eye of the said shuttle, it previouslyhaving been made fast to a suitable filling-end holder, may slipdownwardly and inwardly past the said wing or finger without beingdetained or broken.

It will be perceived that, asin my prior pat.- ent, the replenishingdevices are under the operative control of the change-shaft m. As in thesaid patent, for the purpose of enabling the change-shaft to be operatedat the required time it is provided with a sprocketwheel m, and asprocket-chain m extends around the said sprocket-wheel and also arounda second sprocket-wheel m loose on a rotating loom-shaft, herein thecam-shaft c, a clutch being employed in connection with the saidmechanism for the purpose of permitting the change-shaft to be placed inand out of driving relations with the cam-shaft. One portion of theinvention comprises improvements in the said clutch and in thecontrolling or operating means therefor. In the present embodiment ofthe invention the members of the said clutch consist of a movable dog mthat is pivoted upon an arm m fast with the sprocket-wheel m and a toothm, that is provided at the periphery of a disk m fast upon the camshaft.A spring m acts on the dog with a tendency to bear its engaging end intothe path of rotation of the 'tooth, and when such spring is permitted toact the engagement of the dog with the tooth causes the sp rocket-wheelm to rotate in unison with the cam-sh aft, and thereby occasions therotation of the change-shaft through the connections which have beendescribed.

For the purpose of determining the times of engagement of the dog withthe tooth and of its disengagement therefrom I provide a controllingdevice in the form of a clutchdog disengageiy'which itself is under theoperative control of the weft-indicator devices.

I have shown a simple form of clutch-dog controller ordisengager hereinat n. It consists of a slide mounted to move endwise through fixedbearings n n on the loom-frame. The rear end of the said disengager isdesigned to cooperate with the tailof the clutch-dog. A spiral spring 92surrounding the slide and compressed between a bearing n and a collar nfixed on the slide, acts with a tendency to retract the rear end of thedisengager out of the way of the clutch-dog.

It is to be understood that in practice the construction and arrangementof the clutch devices and controller or disengager may be variedsomewhat.

As a convenient means of actuating the clutch-dog disengager under theoperative control of the weft-indicator devices I provide the cam-disk aThis cam-disk in some of its characteristics and relations bears asimilarity to the cam-disk of my prior patent. It is mounted upon apivot 72 on the loom-frame in position to engage with the saiddisengager. It is furnished with projections 17, M, which are separatedby intervening depressions. The cam-disk n stands normally with one ofits projections in engagement with the clutch-dog disengager, as

in Figs. 2 and 11. By the said projection the disengager is maintainedin position to hold the clutclrdog m disengaged from the clutchtooth in,and consequently the change-shaft remains at rest. During this rest ofthe change-shaft the clutch-dog stands with its tail under the end ofthe disengager it, as in Fig. 2. An advance of the cam-disk n to theextent of one step will present a depression thereof to the clutch-dogdisengager n. This will permit movement of the latter under theaction'of spring m and by such movement of the disengager the clutch-dogwill be left free to be moved by its spring m into the path of rotationof clutch-tooth m As soon as the clutch-tooth comes around in therotation of the camshaft and engages with theclutch-dog the change-shaftwill be caused to begin to rotate. Thereby the working of the variousinstumentalities which are under the operative control of the saidchange-shaft willbe instituted. As long as a depression of the cam-diskremains presented to the end of the clutch-dog disengager the latterwill remain in its inoperative position, the clutch devices will remainin operation, and the to tation of the change -shaft will continue."When, however, a subsequent advance of the cam-disk brings a succeedingprojection on the cam-disk around against the disengager, i t forces thelatter into operative position again. \Vhen next after this happeningthe clutchdog comes around to the disengagcr, as it passes thedisengager its tail will wipe against the latter, the result being toturn the clutchdog on its pivot and disengage it from the clutch tooth.Following this action the change-shaft will come to rest, while the tailof the clutch-dog is still in contact with the disengager, as in Fig. 2.

The cam-disk n is moved intermittingly under the operative control ofthe weftindieating devices. The means of effecting and controlling suchmovement may be varied to meet the requirements of practice. Forexample, the said cam-disk is provided with a ratchet-wheel at, (shownin dotted lines in Fig. 2 and in full lines in Fig. 11,) the saidratchet-wheel being engaged by a pawl n carried by an arm n on theindicator rockshaft n. The said indicator rock-shaft is shown provided,as usual, with an arm 11 extending up into position to .be acted againstby the forward end of the slide a of the usual weft-fork 02, adjacent tothe driving end of the loom. A spring 01 connected with the tail of pawl02. and with arm a operates to hold the pawl in engagement withratchet-wheel it. Each time the said slide a is pushed forward inconsequence of the engagement of the usual gooscneck 71 with the saidweft-fork n the indicator rock-shaft is rocked and operates to advancethe camdisk a one step.

So long as the working weft-supply continues in proper condition thecam-disk will not be moved. Assuming, however, that in the flight of theshuttle toward the driving end of the loom no weft is laid in front ofthe weft-fork at, the engagement of the gooseneck a with the tail of thesaid weft-fork n in the next ensuing forward beat of the gooseneck willcause the indicator rock-shaft n to be rocked and the cam-disk or" to beadvanced one step, carrying the projection u away from the forward endof the clutch-dog disengager 7t and bringing the next succeedingdepression of the cam-disk in line with the said end. This permits'spring a to advance the disengager into its inoperative position,freeing the clutch-dog and allowing it to be placed by its spring inposition to engage with the clutch-tooth m with the result that thechange-shaft is set in motion and the weft-replenishinginstrumentalities are brought into action. The subsequent advance of thecam-disk 07. which brings the next projection n around into actionagainst the clutch-dog disengager, and thereby provides for thedisengagement of the clutchdog from the clutch-tooth, is arranged tooccur shortly prior to the completion of the rotation of thechange-shaft and at or near the completion of the working of theinstrumentalities which are under the operative control of thechange-shaft. In some cases the said subsequent advance of the cam-diska may be effected by other means than that which is disclosed herein.Preferably, however, especially when employing weft-fork devices such asnow are in use, as a, due, I utilize the said weft-fork n and thedescribed intermediate devices for occasioning each of the successivemovements of the cam-disk.

The actuating mechanism for the weft-replenishing instrumentalities isarranged to extend the operations of such instrumentalities throughout apredetermined period corresponding with more than two revolutions of thecrank-shaft of the loom, and consequently the action of theweft-indicator devices will be repeated one or more times before thefirst pick of fresh weft is laid in a shed of the warps. Each of suchrepetitions of the said action of the weft-indicator devices will resultin advancing the cam-disk one step. The spacing of the cam projectionsit apart on the cam-disk n is calculated, therefore, according to thenumber of such actions during the period while replenishment is beingeffected, and preceding the first pick of the fresh shuttle, in orderthat the last of such actions preceding the first pick of the freshshuttle may bring a projection 12 around to act upon the disengager nand move the same into position to disengage the clutchdog m fromclutch-tooth m.

The extension of the operations of the weftreplenishinginstrumentalities throughout a period corresponding with a predeterminednumber of revolutions of the crank-shaft greater than two is providedfor, partly with the object in view of affording ample opportunity forthe performance of the various operations which are incident to thereplenishment of the workingweft supply and of securing the desired easeand safety of action in effecting such replenishment.

An object in view in the case of the loom of my prior patent is to causethe first pick of fresh weft after the replenishment of the working-weftsupply to he introduced into that shed in the round or cycle of shedformations which was deficient in its supply of weft or filling at thetime of the detecting action of the weft-indicator devices which broughtabout the weft replenishment.

I provide in the loom of my prior patent means for suspending theweaving at the time of replenishment during a plurality of shedformations, beginning the count with the said shed, and for resuming theweaving in season to enable the first pick of fresh weft to be laid intoa reopening of the said shed.

The suspension of the weaving is effected in the patent by arresting thepicking, which renders it possible to extend the operations that areincidental to weft replenishment through as many revolutions of thecrankshaft as may be desired. I have herein projoined to the tailthereof a connection 0 ex-v vided an improved arrangement for enablingthe picking to be arrested. The said arrangement is shown in Figs. 1 and2. In the said figures, 0 designates the picking-tappet at the changeend of the l0om,the same being mount ed, as usual, upon the cam-shaft c.

The picking rock-shaft is designated. 0'. The arm at the rear end ofsuch rock-shaft carrying the bowl for engagement with the said tappet isdesignated 0 while a depending arm at the forward end thereof isdesignated 0 An arm 0 is hung loosely to a ing 0 on the forward end ofthe picking rock-shaft 0 (see dotted lines in Fig. 1) and carries a dog0 constructed to engage with arm 0 Herein the said dog is formed with ahole or notch therein, as in dotted lines in Fig. 1, to receive the freeextremity of arm 0 and is drawn into engagement with said extremity whenthe arms are near together by means of a spring 0 connected at one endwith the dog and at the other with the arm 0 The arm 0 isconnected bythe lug-strap 0 with the picker-staff 0 at the change end of the loom.

For the purpose of disengaging the dog 0 from arm 0 when required thesaid dog has tending upward and thence partway around adirection-changing guide-sheave 0 suitably supported on the loom-frame,the rear end of the said connection being joined to a lever 0 The saidlever is provided with a pin or roller 0 bearing against the peripheryof the cam 0 on the change-shaft m. The said cam is termed by me thepicking-c011 trolling cam When dog 0 is engaged with arm 0 thepicker-staff 0 is actuated every time the picking rock-shaft 0" isrocked by means of tappet 0. When the dog is disengaged from the saidarm, the picker-staff remains at rest.

The cam o is shaped to hold the dog o out of engagement with the arm 0until just prior to the resumption of the normal working of the loom.This resumption is caused to take place at the proper time to cause thefirst pick of the fresh shuttle tobe made through a reopening of theshed which was deficient at the time the weft-fork n acted to institutethe working of the weft-replenishing instrumentalities. As in my priorpatent, this reopening of the same shed may be at the end of a singleroundor cycle of shed formations or at the end of a multiple of suchrounds or cycles,according to the circumstances in practice.

The detecting action of the weft-fork n and cooperating devices occursonly after the flight of the shuttle from the change end of the loom tothe driving end thereof. It is apparent, therefore, that if the weftshould first prove deficient in the flight of the shuttle in the reversedirection'. 6., from the driving end of the loom to the change endtherewould be a delay of one pick before'the said weft-fork and cooperatingdevices would act. In the loom of my prior patent there would be a newshed formation for the said pick. Consequently, inasmuch as thepick-finding instrumentalities which have been described thus faroperateonly to recover the shed which was opened for the pick of the shuttlefromchange end to driving end, the true shed would not be recovered inthe event of breakage or failure of the Weft in the flight of theshuttle from driving end to change end in the absence of specialprovision therefor.

My present invention comprises devices by means of which I am enabled tosecure a recovery of the true shed in case the deficiency of weftpresents itself in the flight of theshuttle from driving end to changeend. These-devices I will now proceed to describe.

I provide auxiliary weft-fork devices which are arranged to operateafter the flight of the shuttle from the driving end of the loom to thechange end thereof. The said auxiliary weft-fork devices comprise theweft-fork 19, (see Figs. 1, 2, 6, and 7,) the slide p, supporting thesaid weft-fork, the gooseneck p and the actuating-cam p onthe cam-shaft.When the gooseneck 19 engages the weft-fork p, in case of absence ofweft after the flight of the shuttle from the driving end of the loom tothe change end, and forces the supporting-slidepf forward, the saidslide presses-forward the arm 19 which last has its upper end arrangedin front of the said slide and its lower end pivoted to the frontcross-girth a The said arm p is connected with devices by means of whichto occasiona modification in the working of the shedding cams ortappets. This modification of the said working is intended to cause thefirst pick of fresh weft to be received in the shed which was found tobe deficient by the action of the auxiliary weftfork devices. In orderto secure this result, it is necessary to compensate for the fact thatthe auxiliary weft-fork devices act for the pick next in advance of thatfor which the regular weft-fork devices act. The presentation of thesaid shed at the proper time to receive the said first pick of freshweft may be eifectuated variously in practice. In the present embodimentof the invention I have provided for temporarily arresting the rotationof the shedding tappets or cams. Thus I have so arranged that when theauxiliary weft-fork devices act in consequence of a deficiency of weftin the shed after the flight of the shuttle from the driving end of theloom to the change end thereof a dwell in the shed formations for aperiod corresponding with one pick is occasioned. In other words, inthis embodiment of the invention the procession of shed formations iscaused to fall behind one step, and thereby I offset the fact that theregular weftfork does not act until after the pick next succeeding thatin which the deficiency of weft first manifests itself.

The dwell in the shed formations is occasioned herein by means ofdevices operating to leave the shedding tappets or cams at rest for aperiod corresponding with one pick.

The shedding tappets or cams are designated q q q, Figs. 1, at, and 5.The shedding-treadles are shown at q q q. The tappets or cams q q q aremounted on the jackshaft g which last is driven by means of a train ofgears g g g and q. The gear q is mounted on the cam-shaft c. It is loosethereon and provided with a clutch-face (1 A clutch-sleeve g isfeathered upon the camshaft and is constructed and arranged to engagewith the clutch-face The said clutchsleeve is under the control of ashipper-lever q. A spring q acting on the said shipperlever, holds theclutch-sleeve normally in engagement with the gear q, and thereby thejack-shaft is driven. The shipper-leverq is mounted to swinghorizontally on a pivot q applied to the rear cross-girth (1 To the rearend of shipper-lever a dog q is hung,with capacityto move verticallyabout a pivot the said dog being acted upon by a spring (1 tending tohold the free end thereof raised. \Vith the said dog is connected oneend of a connection 13 ext-ending from the arm 17*, the said connectionbeing made flexible in part to enable it to pass around thedirection-changing guide-sheaves p 19. From the guide-sheaves theconnection 235 extends upwardly to the dog 1 hen the auxiliary weft-forkp is engaged by the gooseneck p and the slide 1) and arm 19 are pushedforward, the pull which is transmitted through the connection 11 drawsdown the free end of the dog q into the path of rotation of a sidetappet g on a disk (1 fast on change-shaft m. This occurs at a time whenthe change-shaft m is standing still; but the dog is held in itsdepressed position by means of a latch 1 acted upon by a spring q".lVhen subsequently the change-shaft is set in rotation through thedictation of the regular weft-fork n and the devices cooperatingtherewith or controlled therefrom, the said side tappet (1 acts againstthe dog q, and thereby turns the shipper-lever (1 on its pivot anddisengages the clutch-sleeve g from the gear g. This disconnects thejack-shaft g from the cam-shaft and arrests the rotation of the former,with its shedding tappets or cams. After the withdrawal of theclutch-sleeve from the gear 1 the continued rotation of the former inunison with the cam-shaft brings the outerv faces of its teeth aroundinto position to bear and slide against the outer faces of the teeth ofthe clutch-faceq of gear q. The two sets of teeth are of such length,measured circumferentially, that they hold the clutch members apartuntil after the completion of approximately one revolution of thecrank-shaft of the loom. The faces of the teeth of the clutch-sleeve aremade inclined, in order to permitsaid teeth to slip gradually into thespaces between the teeth of the clutch-face Q7 of gear Q6, and therebydiminish the shock which is incident to the rengagement of the clutchmembers. Sufficient play between the teeth of the two 0pposing sets isprovided for to permit of easy entrance of each set of teeth among theother set.

In order to enable dog q to be moved by its spring (1 out of the path ofrotation of the tappet (1 after the latter has occasioned the requiredmovement of the shipper-lever q", a second tappet (1 is provided on thedisk q, it acting on the latch (1 at the proper time to disengage thelatter from the said dog g.

It is necessary that the auxiliary weft-fork devices should be renderedinoperative after the regular weft-fork devices have been brought intoaction In cases in which the deficiency of weft occurs in the flight ofthe shuttle from the change end of the loom to the driving end and isduly detected by the regular weft-fork devices it is unnecessary for theauxiliary devices to act at all. So, also, in cases of deficiencyoccurring in the flight of the shuttle from the driving end to thechange end, the auxiliary weft-fork devices, after they have acted andhave operated to modify the working of the shedding instrumentalities,should be prevented from acting a second time subsequently to theensuing detecting action of the regular weftfork devices.

Vith the foregoing ends in view I have provided the followinginstrumentalities for controlling the working of the auxiliary-weftforkdevices: Upon the indicator rock-shaft n is made fast an arm 71 (SeeFigs. 1, 2, 6, '7, and 15.) This arm extends rearwardly adjacent to andbelow the slide 19 for the auxiliary weft-fork 19. Through one ofseveral holes n in the said arm passes a wire a, carrying a collar 92thereon above the arm, the said wire being attached at its upper end toa lever n, which is pivoted at n on the slide 1). The rear end of thesaid lever is bent laterally (see Figs. 6 and 7) and extended above apin a, projecting rearwardly from the weft-fork. The detecting action ofthe regular weft-fork devices in rocking the indicator rock-shaft 12serves to raise arm n and, through the described connections, operatesto turn lover a, so as to cause it to bear upon the pin 01 This tiltsthe auxiliary weft-fork 1), so as to prevent its tail from being engagedby the gooseneck 19 The goosenecks 12 and 19 act for successive picks;but in order to enable the regular weft-fork devices to operate throughthe lever 01 to prevent the auxiliary weft-fork p from becoming engagedby gooseneck p the cam 71 for actuating the main gooseneck 71, is madewith adwell, which holds the latter forward at each beat thereof untilafter the auxiliary gooseneckp has been advanced to feel for theauxiliary weft-fork 1). (See Fig. 14:.)

It has been stated herein that the spacing of the cam projections itapart on the camdisk a is calculated according to the number of actionsof the weft-indicator devices during the period while replenishment ofthe working-weft supply is being effected and preceding the first pickof the fresh shuttle. The particular form of the said cam-disk which isshown in Fig. 2 has been fixed by the fact that the illustrated loom hasbeen designed with especial reference to the employment of either two,three, or six harnesses, the parts being constructed and combined torestart the picking and the normal working of the loom after asuspension thereof, including the sixth shed formation, beginning thecount with the shed formation preceding the detecting action of theregular weft-fork devices. The seventh shed is a repetition of the saidfirst shed whether two, three, or six harnesses are employed, (six beinga multiple of both two and three,) and consequently in cases where thedeficiency of weft occurs in the said first shed the weaving will beresumed by the pick through the seventh shed without any break in thecontinuityof the weave of the fabric being produced.

I have herein represented provisions for operating three harnesses; butthis is merely by way of illustration, and the manner of utilizing theinvention in connection with other numbers of harnesses will be obviouswithout further explanation.

In the present case in order to secure the resumption of the normalworking of the loom in seasonfor the seventh pick the changeshaft isdriven from the cam-shaft by driving connections giving the change-shafthalf the speed of the cam-shaft, thereby causing the change-shaft tomake one revolution to four revolutions of the crank shaft. Thegooseneck 01 engages with the regular weftfork and acts to move theWeft-fork slide n forward in the loom at about the time of the secondpick of the failed shuttlet'. 6., the pick back from the driving end ofthe loom to the change end thereof. The next four picks (by which shouldbe understood also revolutions of the crank-shaft) are occupied by theworking of the replenishing instrumentalities, the actual picking of theshuttle being arrested in consequence of throwing out of action thepicking devices at the change end of the loom, after which the normalworking of the loom is reinstituted in season for the seventh pick.

Having reference to Fig. 2, it will be seen that the first advance ofcam-disk n (it occurring at about the time of the second pick) willcarry the acting projection 01? away from clutch-dog disengager n andbring a depression in line with the latter which will permit thedisengager to assume its inoperative position. The second advance of thecam-disk (it occurring at about the time of what ordinarily would be thefourth pick) still leaves the depression in line with the disengager.The third advance of the cam-disk (it occurring at about the time ofwhat would ordinarily be the time of the sixth pick) brings the nextprojection 11 around, so as to cause the clutch-dog disengager to bepushed rearwardly. This disengages the clutch-dog m and renders thechange-shaft m inoperative.

Vhen using a number of harnesses other than two, three, or six, Icontemplate sometimes varying the relative speed at which thechange-shaft is driven through change in the proportions, &c., of thedriving connections in order to restart the picking and normal workingof the loom at the end of a round or cycle of shed formations or amultiple of such round or-cycle. When this is the case, the spacingapart of projections n will be varied proportionately. I prefer,however, to retain in theloom the same driving connections and continueto drive the change-shaft at the same relative speed as provided forherein and to secure the required different number of shed formationsprior to the resumption of weaving by permitting theweft-indicatingdevices to act idly one or more times before the clutchis permitted to act. This may be effected by simply increasing thecircumferential length of projections of, as indicated-in Fig. 12, so asto permit the cam-disk n to be advanced one or more times before thesucceeding depression is brought around into position to receive the endof the clutch-dog disengager. This will permit the regular working ofthe loom to continue with the failed shuttle for two, four, or morerevolutions of the crankshaft after the first detecting action of theweft-indicator devices before the working of the loom is modified andthe weftreplenishing' instrumentalities are brought into action. In somecases an intermediate projection, as a Fig. 9, may be provided on thecam-disk a This will act after the weftreplenishing instrumentalitieshave begun to work andhave ejected the failed shuttle. It

\ will move the clutch-dog disengager to unclutch the change-shaft andsuspend the weftreplenishing operations for two, four, or more picks,after which the movement of the camdisk that is occasioned by the actionof the weft-indicator devices will bring the next depression of thecam-disk around in position to allow the clutch-dog disengager to resumeits inoperative position. The change-shaft thereupon will be clutched tothe camshaft again and the working of the replenishing instrumentalities will be proceeded with to completion.

The speed-changing devices, by means of which the speed of the loomautomatically is reduced for the performance of the weft-replenishingoperations and afterward is restored for the resumption of the normalworking of the loom, are herein as in my prior patent. They comprise thecam-disks r and s on the change-shaft 'm, the arms 4 and s, acted uponby the said cams, the belt-shifters r and 5 with which the said arms areconnected, the springs 4: and s acting to move the belt-shifters inopposition to the said cams,

the fast-speed driving-band r, the slow-speed driving-band 8 the usualfast and loose band-pulleys r and 4- respectively, on the driving-shaftb, for cooperation with the fastspeed driving-band T and thesupplemental fast and loose band-pulleys s and s, respectively, on thesaid driving-shaft, for cooperation with the slow-speed driving-band s.A pin 25 or its equivalent is applied to the front of the lay-beam belowthe inner end of the shuttle-box at the change end of the lay to catchand detain the inner end of the ejected shuttle as the latter falls fromthe shuttleboX. This pin acts to uphold the said inner end of theshuttle, so that the outer end of the latter shall descend first.

The usual shipper-handle for use in stopping the loom by hand whenrequired is shown at a, Fig. 1.

The tines of the weft-forks in the form thereof which is illustrated inthe drawings extend downward from or close to the pivotal supports ofthe weft-forks. This gives a better distribution of the weight than inthe case of ordinary weft-forks and lessens the tendency of the tail ofthe fork to rebound upwardly away from the gooseneck in running the loomat high speed. The forks are shown set as near the lay as possible inorder that the weft may be brought into contact with the tines thereofas early as possible in the forward beat of the lay, so as to permitearly working of the goosenecks. In order to enable the heads of thegoosenecks to engage with the tails of the said weft-forks, the saidheads are extended rearwardly in the form of rigid hooks, as shown, thesaid heads being also arranged at a height above the top of the workingshuttle on the lay in order to avoid making contact with the saidshuttle in case it should lie on the raceway in front of eithergooseneck at the time of the advance of the lay.

Fig. 8 illustrates a modified pick-governing arrangement, such as iscapable of being employed with another form of picking mechanism. InFig. 8 the pickingtappet 0 acts against a bowl or roller 0 and therebydepresses a treadle 0 which is pivoted upon a horizontal pivot-pin 0 toa bracket 0 fastened to the rear cross-girth a IVith the front end ofthe said treadle is engaged the strap 0 the latter passing over theguide pulley o and being connected with the pickerstafi" 0 at the changeend or supply end of the loom. For the purpose of rendering the saidpicker-staff inoperative when required relative lateral shift isprovided for between picking tappet or cam 0 and the bowl or roller 0Herein the said shaft is provided for by mounting the said bowl orroller 0 upon a support 0 which is pivoted on treadle 0 at o by avertical pivot, so as to be free to swing laterally. For the purpose ofswinging the support 0 on treadle 0 so as to move the bowl or roller 0into and out of operative position with relation to the picking tappetor cam o, the said support is provided with a lateral arm 0 to which isconnected by a pin 0 a short link 0 The rear end of the said link 0 isconnected by a horizontal pivot at 0 with a slide 0 working through aslideway in the rear cross-girth a. The rear end of the said slide isforked and carries a crosspin 0 working in a longitudinally-extendingslot 0 in an arm or lever 0 The said arm or lever is pivoted at 0 to abracket 0 fixed to the rear cross-girth a, and carries a pin or roller0, bearing against the periphery of the picking-controlling cam 0 on thechangeshaft on. A spring 0 connected with the arm or lever 0 holds thepin or roller 0 into contact with the said cam. In the normal or workingpositions of the parts the pivoto is in horizontal alinement with thepivot 0 of the picking-treadle 0 I do not lay claim, broadly, herein tothe combination, with the Weft-indicating devices, weft-replenishinginstrumentalities, &c., of pick-finding instrumentalities operating torecover the true shed corresponding with the first deficient pick ineach direction, nor to pick-finding instrumentalities under operativecontrol of the change-shaft to shift the shedding mechanism to reopenthe required shed, inasmuch as claim thereto is made in my pendingapplication, Serial No. 726,732.
